3VU13, 3VU16 circuit-breakers are compact circuit-breakers with rated current up to 63A, used for starting, disconnecting and overload and short-circuit protection of motors or other loads, 3VU13 and 3VU16 can also be used as motor phase protection. When used for motor or equipment protection, the above circuit-breakers are equipped with overcurrent instantaneous release and reverse time delay overload release.
The document lists Siemens low‑pressure control equipment, including circuit‑breakers up to 63 A, various contactor combinations and overload relays. Technical tables give current and voltage ratings for the 3VU13 and 3VU16 product families.
Tables on pages 4‑6 show the rated currents (e.g., 0.1‑25 A for 3VU13) and voltage ranges for each model, allowing engineers to select the appropriate device for their applications.
| 3VU13 current rating | 0.1~25A |
|---|---|
| 3VU16 current rating | 1~63A |
| 3VU13 voltage rating | 63A |
| 3VU16 voltage rating | 63A |
The 3VU13 model is rated for a current range of 0.1 to 25 A.
